Question

what is the domain of the function in this table?\
\

x	y	\
---	---	\
2	1	\
3	4	\
4	4	\
5	2	\

\
a. (2, 1), (3, 4), (4, 4), (5, 2)\
b. (2, 1)\
c. {1, 2, 4}\
d. {2, 3, 4, 5}

Explanation:

Step1: Recall domain definition

The domain of a function is the set of all input values (x - values) for which the function is defined.

Step2: Identify x - values from the table

From the given table, the x - values (input values) are 2, 3, 4, and 5.

Step3: Form the domain set

We collect these x - values into a set. So the domain is the set containing 2, 3, 4, and 5.

Answer:

D. {2, 3, 4, 5}
